Aira is cosplaying as Souji Okita from Hakuouki: Shinsengumi Kitan. Souji Okita is loosely portrayed in the Japanese-only otome PS2 game, Hakuouki (薄桜鬼), along with other Shinsengumi members. They are samurai who develop vampiristic qualities as the game progresses. He is portrayed more prominently in the 2010 anime adaptation of the game Hakuouki: Shinsengumi Kitan.In the Japanese video game Sengoku Rance by Alicesoft, a female version of Okita plays a minor role, Okita Nozomi. Okita Nozomi can be recruited from the Shinsengumi in the game as a commander, and is one of the best swordsmen in the game. She is also seen constantly coughing up blood and is later diagnosed with the "Cough-Cough Disease".The digital comic "Okita and the Cat" deals with the anecdotal last days of Okita Souji. The former swordsman is depicted as a pleasant raconteur despite his disease, though he's secretly frustrated at his inability to stand by his comrades. The comic, by Josh Hechinger and mpMann, was released for Apple mobile devices in August 2010 through Arrow Publications.
